(1S)-1-amino-1-phenylpropan-2-ol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of (1S)-1-amino-1-phenylpropan-2-ol (0.43 g, 2 mmol) in H2O (2 mL) was added potassium cyanate (0.23 g, 2.7 mmol) and the contents were stirred at ambient temperature for 2 hr. The solid thus obtained was filtered and washed successively with H2O (2×5 mL) and dried in air to afford 1-((1S)-2-hydroxy-1-phenylpropyl)urea. MS: [M+H]+ m/z 195. The solid thus obtained was filtered washed successively with H2O (2×5 mL) dried in air
